Source (Damage Condition Type)

Checks whether this damage was dealt by an Apoli power, and optionally which power it was and which source granted it. With no fields set it matches any damage a power caused, and nothing a sword, a fall or a creeper did.

Type ID: apoli:source

Fields#

Field	Type	Default	Purpose
power	Identifier	optional	The power that dealt the damage. Omit it to match any power.
source	Identifier	optional	A source the power was granted from — an origin layer, a skill tree, a global power set or whatever granted it. Omit it to match any source.

What counts as a source#

Every power a holder has is filed under the source that granted it, which is what /apoli:power sources prints and what the apoli:power entity condition’s own source field matches. Origins files its powers under <namespace>:layer/<layer>, so "source": "origins:layer/origin" means “anything the player’s origin gave them”.

Attribution follows the power through delayed and nested actions, so a hit from an apoli:delay chain or a projectile’s bientity_action_on_hit still names the power that started it.

Examples#

Take no damage from anything a power did:

{
  "type": "apoli:source"
}

Immune to one specific move:

{
  "type": "apoli:source",
  "power": "example:fire_breath"
}

Everything an origin’s powers do is halved, while ordinary weapons hurt normally:

{
  "type": "apoli:modify_damage_taken",
  "modifier": {
    "operation": "multiply_total",
    "value": -0.5
  },
  "damage_condition": {
    "type": "apoli:source",
    "source": "origins:layer/origin"
  }
}

Mundane damage only — weapons, fire, falling, but nothing a power caused:

{
  "type": "apoli:source",
  "inverted": true
}

Notes#

• For “was this a melee hit” or “was this a projectile”, use apoli:type, apoli:projectile or apoli:in_tag — this condition answers a different question.
• For “did the attacker have origin X”, wrap an entity condition in apoli:attacker instead; source matches how the power was granted, not who the attacker is.
• Attribution is tracked from the first data pack that loads this condition onwards, and only on the server.
